Default aerator

Can you use an air compressor and a filter with a stone attached to aerate your wort? What would be the difference between that and using a fishtank pump?

An air compressor is likely mega-overkill for this kind of task. But, assuming you can throttle it back to a reasonable volume/pressure and assuming you can get an air filter on there, it should work fine. Good luck!

If you have ever drained your compressor tank, you would not even think once about using it for brewing! Depending on your humidity as the air gets compressed water will pool in the tank. There is a drain valve on the bottom to let this water out. WARNING !!! Make sure the tank is empty then open this valve and take a look at what comes out. I did this after about a month or so of use, the only thing swamp water has over this water is mosquito lava. And don't think that this water in not being blown out through the hoses. Run the air over a paper towel a few times and take a look, it will be damp for sure.

If you want to aerate your wort properly, use Oxygen. Atmospheric air is only like 20% Oxygen.

Do you have to get a regulator of some sort for those or do they come with a valve? I can't tell from the photo.

You have to get the regulator. I ended up buying a Brazing kit at HD that had the Regulator and a bottle of O2. Wasn't the cheapest route to go but I didn't have time to track one down on line. I needed it right then.

I use one of these to infuse the oxygen:

The regulators are expensive and hard to come by these days thanks to some kind of manufacturing snafu. Most places that have them are charging a ransom for them. Oxygenation is a nice alternative to aeration, but requires a bit more attention.

Williams Brewing has them too, but they're both charging $50. A few months ago they could be had for half that.
